He's like fire and ice and rage. He's like the night, and the storm in the heart of the sun. He's ancient and forever. He burns at the center of time and he can see the turn of the universe. And... he's wonderful.
He has saved your lives so many times and you never even knew he was there. He never stops. He never stays. He never asks to be thanked.

He is a man who can change his face. He travels in his magical machine, through holes in time and space.

He is the Last of the Time Lords, from the planet Galifrey, a lonely angel, a wanderer. He is a man without a home, and is always searching for a companion.

The monsters and the doctor, it seems you cannot have one without the other. He is completely terrifying, but so, so exciting.
His name...is the Doctor.

The Doctor is the last of his race, the Timelords, which was destroyed in the Time War. He was born in Gallifrey and travels through time and space in his TARDIS, which looks like a blue police box. Originally the TARDIS (Time And Relative Dimensions in Space) was able to change its appearance to blend in to its surroundings, but that feature has been long broken, much like many of its functions.

The Doctor often travels with companions. His greatest rival is The Master. His enemies are the Daleks.

He may sound like he's from the North, but in actuality, he's an alien, and lots of planets have a North for your information.

He is like fire, burning through time, as old as forever the past in his prime. You'll see his blue spaceship materialize, he'll look out and say to you, RUN FOR YOUR LIFE!
